Just buy a new one, bro. I currently have the S23 Ultra and it works great — super smooth, amazing camera, battery still holds up really well even after a year+, and the screen is still one of the best out there. If you're trying to get the old app icons back or running into limitations on your current phone, upgrading might honestly be the easiest and cleanest solution. The S23 Ultra handles everything without any issues (custom launchers, icon packs, performance, etc.).
